2017


• Renew able Energy Capacity is doubled in last 4 Years.

• Target up to year 2022 is 175GW (as per International

Solar Alliance summit 2018). Now upgraded 227 GW

• Solar power capacity increased by over 8 times in last 4 years from

2630MW to 22000 MW with record 100 billion+ units of renew

electricity generated last year.

• Wind power capacity increase by 1.6 times in last 4 years from

21000 MW to 34000 MW.

• Transparent bidding process of Government led to significant

reduction in per unit cost of Solar & Wind power.

500kW)

The location of the site is flat and the PV modules are generally oriented towards the same

direction without any blockage

Generally ≥5MW even GW level

Power generation with 10KV or 35KV access to power grid，far from load, unable to be

consumed locally

String PV

Photovoltaic module≤5 sets connected to grid inverter by string form

Flexible location，installed in hills，roof etc. Module orientation is

inconsistent

Different capacity，less than 1 MW operable

Power generation with 10KV or 35KV access to power grid，far from load,

unable to be consumed locally

Photovoltaic solution centralized & string



DC arc is more difficult to extinguish,

so DC MCB for PV use only is more

preferred to keep safe.
